Application filed March 9, 1914. Serial No. 823,546.

To all whom it may concern Be it known that-I, Roy DRUMMOND, a citizenof the United tSates of America, and a resident of the city of Seattle,in the county of King and State of Washington, have invented certainnewand useful linprovements in Wrenches, of which the following is aspecification.

My invention has for its aim to provide a tool of the above characterconsisting of two elements whereby a wrench of simple and durableconstruction is obtained to operate in an eflicient manner.

Those features of construction, arrangement and combination of parts onwhich I desire protection are'succinctly defined in the appended claims,and for a full understanding of the same reference is to be had to thefollowing specification and the accompanying drawing wherein:

Figure 1 is an elevation of my wrench. Fig. 2 is an edge elevation, aportion of the pivoted jaw being in section, and Fig. 3

. is a view similar to Fig. 1, the pivoted jaw surface.

being employed in a difierent position.

It may be preliminarily stated that in-the preferred embodiment,illustrated in the attached drawings, there are employed a shank,provided with a curved jaw face and a serrated jaw face, and a jawpivoted to the shank for movement to a position to cooperate, witheither of the shank jaw faces.

Referring by like characters of reference to like parts throughout theseveral views of the drawings and the specification, 1 designates ashank conveniently formed on one end portion to provide a handle andhaving its opposite end portion fabricated in the form of a fixed jaw 1With'a curved jaw face 2 on one side and on the opposite side a seriesof serrations 8 constituting another jaw face. The jaw 4.- is pivoted,as by pin 5, to the fixed jaw 1 and comprises a pair of plates providingspaced arms or extensions 6 to receive the aforesaid fixed jaw, theouter end portions of the plates being pressed together to form thereduced solid jaw body 7. The jaw is reduced, as shown, to direct-1yoppose or lie entirely within the plane of the fixed jaw 1, thisconstruction being: especially advantageous when operating on small orthin nuts as the outer jaw pomay lie flat or flush on a The and of themovable jaw is turned to p: efi'ectively grip so article. Arms 6 have alip or hook 8 to more their inner edges curved or of arcua'te formationand provided with teeth to produce jaw faces 6' adapted for cooperationwith either face 3 or jaw face 9, the latter being formed in a plane, onfixed jaw 1. within the curvature of smooth face 2 whereby a shoulder 2is formed to afford a more secure grip on a pipe. A shoulder 7, disposedbetween jaw body 7 and faces 6, opposes lip 8 and defines therewith apocket or seat for a nut. The jaw face of body 7 and faces (5 are eachadapted for cooperation with face 3. Swinging the jaw 4 over the end ofjaw 1 from the face 2, which is especially adapted for nuts and the likehaving straight edge portions, the jaw i may be used in cooperation withthe serrated face 3 for operating on pipes or the like. This latterarrangement may also be employed for nuts when a shorter leverage isrequired.

The foregoing detailed description has been given for clearness ofunderstanding only, and no undue limitation is to beunderstoodtherefrom, but the appended claims are to be construed as broadly as ispermissible in view of the prior art.

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, of the United States of America,.is:

1. A wrench comprising a shank element formed with a fixed jaw having acurved smooth jaw face and a serrated jaw face leading from the smoothjaw face, and a movable jaw adapted for cooperation with the faces ofthe fixed jaw and having a smooth fiat jaw face formed with opposingshoulders to receive a flat surface and a curved serrated jaw face.

2. A wrench comprising a shank element formed with a fixed jaw having acurved smooth jaw face and a serrated jaw face leading from the smoothjaw face and lying within the plane of curvature of the latter face toprovide a shoulder between the faces, and a movable jaw adapted forcooperation with the faces of the fixed jaw and having a flat jaw faceformed with opposing shoulders to receive a fiat surface and la curvedjaw face to oppose the serrated face of the fixed jaw.

3. A wrench comprising a shank elementformed with a fixed jaw having asmooth face and a serrated face on one side and a curved serrated faceon the other side of the fixed jaw, and a jaw pivoted to the fixed jawand formed with a flat face to cooperate shank element and provided witha curved with the smooth face of the fixed jaw and a jaw face and a flatjaw face leading from the curved face to cooperate with the adjacentlatter, said pivoted jaw also being formed 15 serrated face of saidfixed jaw, said pivoted with a shoulder extending outwardly from 5 jawbeing adapted to swing to oppose the the flat jaw face at the 1nner endthereof curved serrated face of the fixed jaw whereto be intermediatethe jaw faces. by either jaw face of the pivoted jaw is Signed atSeattle, Washington, this 10th adapted for cooperation with the lastnamed day of February, 1914. a 7
